This sealing compound was developed to provide strongest adhesion and flexibility when used in joints of concrete, flexible surfaces, walls, bricks, stone and glass. There are many such materials in use like Rubberized Bitumen, Siliconised Rubbers, Acrylics, Urethane and Sulphate etc.; however Aerolastic Compound gives far better results than other such products.
The rubber based Bitumen is good only if not heated because once rubber is treated with heat in presence of Bitumen it becomes very hard and flexibility is reduced to half; thus reducing its life. Similarly other products mentioned above including epoxy resins are very expensive to use.
This product which is made with selected Bitumen and Thermoplastics is best due to the reason that if heated man times it will come back to same flexibility and adhesion on cooling. Moreover, price is low and its ability to heat more than once has edge and advantage over similar products in use.
